00133 Check Remote Temperature Sensor 1
00134 Check Remote Temperature Sensor 2
00135 Check Remote Temperature Sensor 3
• ACTIVATION: Remote Temperature Sensor (REMSN1, REMSN2 or REMSN3) is not within the range of
-53 to +158°F (-47 to +70°C.)
• UNIT CONTROL: Engine and Electric Operation: Alarm only.
• RESET CONDITION: Auto Reset when Remote Temperature Sensor is in range or, alarm may be
manually reset via keypad or by turning the unit off, then back on again.
NOTE
Follow the steps below until a problem is found. Once a repair or correction has been made, the
active alarm should clear itself (refer to reset condition above). Operate the unit through the appro-
priate modes to see if any active alarm occurs. Continue with the steps below as necessary.
Corrective Actions:
If a sensor is installed:
1. Check Sensor
a. Inspect sensor and connector. Verify there is no damage to sensor, and no damage, moisture, or
corrosion in connector.
b. Check sensor resistance (Refer to Note 3 in Notes Section) 10,000 Ohms @ 77°F (25°C). Refer to
Table 8–5 for chart of resistances for different sensors.
2. Check Sensor Wiring
a. Inspect connector pins and terminals at sensor, REM connector and
1-3MSM-7, 19, 8, and 30
.
(See wiring schematic Section 10.2) Verify there is no physical damage to harness, and no
damage, moisture, or corrosion in connectors.
b. Place the system in PC Mode. Refer to Note 2 in Notes Section Disconnect sensor from harness.
Check for 3.0 ± 0.1 VDC volts at harness plug between pins. This verifies microprocessor output and
wiring connections to sensor.
If a sensor is not installed:
1. Check Configurations - Any switch/sensor that is not present in the unit should not be Configured “ON”.
Correct Configurations.
2. Check REM Connector - Locate and inspect 10 position connector for optional sensors and switches.
(See wiring schematic Section 10.2). Connector must have cap on, no corrosion or moisture inside con-
nector. If there is a problem with the connector and there are no remote sensors or switches in the unit,
the connector may be removed and each individual wire separated from the others, terminated and insu-
lated with heat shrink.
